Calcium and vitamin D reduce appetite and boost metabolism

Doctors in one study wanted to see what effect a breakfast with low or high levels of calcium and vitamin D would have on fat-burning and appetite later in the day.

Eleven obese people, average age 54, ate a breakfast containing 250 mg of calcium with 12 IU of vitamin D, or 500 mg of calcium with 348 IU of vitamin D. They were allowed to eat whatever they wished for lunch.

Over the next 24 hours, those in the high-calcium/vitamin D group consumed 320 fewer calories than the low calcium/vitamin D group. In addition, those in the high-calcium/vitamin D group had a higher metabolic rate, burned more calories and utilized fat better than the low-calcium/vitamin D group.
